I have a Dell 620i computer running Windows 7 Ultimate. I had an HP Officejet All in One 5600 from my old computer and tried to use it with the new computer with no luck. I purchased a 4500 and am on my second one. HP has been unable to solve my problem.
After installing updated drivers, the printer shows to be disconnected. It works as a scanner, copier, and fax when it is up, but the printer is the big issue. HP has me disconnect the power cord or the USB cord and sometimes it brings the printer to life. But the next day, I am back to the same issue. Changing USB ports does not seem to help.
Any suggestions would be appreciated. I don't see connecting and disconnecting cords at startup as a viable suggestion.
